[texts]A Novel Method for Image Enhancement
In this paper a novel method for image enhancement using PDTDFB (Pyramidal Dual-Tree Directional Filter Bank) and interpolation has been adopted. Generally, in digital images since the different kinds of noise highly affects various image processing techniques it is always better to perform denoising first. Here, first of all the image is decomposed into two different layers namely low pass sub band and high pass sub band after which denoising is being performed on both the layers so as to smoot...

[texts]Image Denoising Techniques Preserving Edges
The objective of this work is to propose an image denoising technique and compare it with image denoising using ridgelets. The proposed method uses slantlet transform instead of wavelets in ridgelet transform. Experimental result shows that the proposed method is more effective than ridgelets in noise removal. The proposed method is effective in compressing images while preserving edges.
